The interspace between adjacent stubs along radial direction was equal to one guide wavelength, a shorting pin was located at the end of the upper radial line waveguide and the space between the pin′s surface and the innermost CTS radiator′s center was half a guide wavelength. As a result, the HPM-RL-CTSA works on standing wave. An antenna prototype with a height of 80 mm and an aperture radius of 285 mm operating at 14.25 GHz has been designed, which has a gain of 35.3 dBi, reaching an aperture efficiency of 47%. The reflectance of this antenna is less than -25 dB and the radiation efficiency is more than 99.0%. The simulated results indicate that this antenna has a power handing capacity of more than 1 GW.]]> 2020/10/21 15:50:32 SUN Yunfei, HE Juntao, YUAN Chengwei, ZHANG Qiang, ZHANG Zehai 2true 2020/10/21 15:50:32 LI Songcheng, LU Junyong, CHENG Long, WU Yiting 1true
